Application filed Ju1y12,

. This invention relates to an improved construction of bracelet hook or end member; and has for its object to provide a I device of this character; having a body portion in which one end of a hook member is pivotally mounted the hook being acted upon by a spring pressing it to operating position.

A further object of the invention is the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings v Figure 1 is a perspective view illustrating my improved hook as connected to one of the bails of a watch.

Figure 2 is a perspective view showing .the body of the hook, ,or-end memben Figure 3 is a perspective view showing the hook member of the device.

.Figure 4 is a perspective view showing the pivot pin with the opera-ting spring wound about it.

Figure 5 shows the hook member as pivotally mounted in the body with the spring acting to press the hook towards closed position.

Figure 6 shows the hook as swung on its pivot to open position away from the fixed tongue.

Figure 7 is a section on line 7-7 of Figure 5 showing the hook pivotally mounted in the body member,

Figure 8 is a perspective View illustrating the hook as being swung into position to engage or disengage the bail of a watch, the fingers of the operator being shown in dotted lines as engaging the sides of the body portion and the back of the hook member. c

It is found in the practical operation of some styles of bracelet hooks, difiicult to disengage the same from a watch bail, some requiring one finger to be inserted beneath the hook to raise the tongue in order to 78183.88 the same which is diflicult particularlywhen on the arm of the wearer, and which difliculty I have overcome in a. simple and lVith these and otllenobjects in view, the

practical way by pivoting the hook member, instead of the tongue member, in the body portion of the device whereby it is only necessary to engage the sides of the body between the thumb and finger with one fingeron the back of the hook to swing them relatively and open the hook for ready engagement or disengagement; and the following is a detailed description of the one construction of my improved hook by which 7 these advantageous results may be accomplished:

\Vith reference to the drawings, 10 designates the body of the hook which is preferably formed from a blank of sheet stock.

folded into box form having a top wall 11, bottom wall 12, and side walls 13. In some cases one end wall 14 may be provided to which the neXt adjacent bracelet element 15 may be attached when desired.

The bottom wall is provided at its open end with a forwardly projecting tongue 16 which may be formed integral with this wall if desired for the purpose of closing the hook. I

The book member 17 of this device is also preferably, formed of sheet stock being folded at one end to form an engaging hook or loop 18 preferably broader than the body member of the device to engage and fit closely in the bail 19 of a watch 20.

The opposite end of this hook is preferably reduced as at 21 forming a neck portion which is provided on its opposite edges with downwardly extending ears 22 pierced as at 23 and this neck portion is arranged to fit between the side walls of the box member 10 and is pivotally secured thereto by means of a pivot pin 24 which preferably extends through the ears 22 and through the pierced walls 13 of the box portion.

In order to press this hook member up into alignment with the front wall of the box member, I have provide a coiled spring 100 shown in Figure 6, to open the hook and permit the passage of the bail or other article to which it is to be attached into and out of the hook.

I have described the tongue portion which is carried on the body member as being rigid, requiring a relative disengaging movement of the hook in attaching the same, but I may in some cases make the tongue resilient to yield and permit an engaging "action without being obliged to swing the hook 1f desired.

The device is very simple and practical in construction, is effective in its operation and its opposite sides may be readlly engaged by the fingers of the operator of the hook and the hook itself pressed downward- 1y to eifect either a connecting or disconnecting action to and from its operating position.

The foregoing description is directed solely towards the construction illustrated, but

I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

"I claim:

1. A bracelet end member having a sheet metal body portion and a sheet metal hook member pivoted to said body portion, said hook being opened by swinging of the hook towards its free edge relative to the body.

2. A bracelet end member having a body portion, a hook member pivoted to said body portion, a hook-closing tongue carried by the body and engageable with the inside of said hook to close the same when in operative position, said book being movable to cause its neck to move towards said tongue to open the hook.

3. A bracelet endmember having a sheet metal box shaped body portion, a separate hook member pivoted at one end in said box and a hook closing tongue rigidly carried by said body and engaging the inside of said hook to close the same.

i. A bracelet end member having a body a portion, a hook member pivoted in said body and swingable towards its free edge relative to said bodyto open position anda springacting between the body portion and the hook to normally press it to closed position. i

5. A bracelet end member having a body portion, a hook member pivoted in said body portion, a spring acting betweenthe hook and the body portion to press it to closed position, and a tongue fixed on the body and engaging the inside of saidhook to close the same.

6. A bracelet end membercomprising a sheet metal hollow body with top, bottom EUGEN PRESTINARI.
